My DD is 3 and has been invited to the birthday party of a preschool friend. As she is so young I plan to stay at the party, however, my husband just informed me that he is working overtime that day. I am thinking of asking if it is OK for my son (17 months) to tag along.
So in general terms my question is:
Is it OK to ask if younger siblings can attend a birthday that they are not invited to? Is it dependent on anything? For example age, place where party is held, etc? Is it OK at any age to simply bring a younger sibling without asking first? As the person being asked, would you provide anything extra for the younger sibling if you say yes, for example a goody bag?
